In an A.P, if first term is 4, `9^(th)` term is 20 then `15^(th)` term is

In an A.P, if first term is 4, 9th term is 20, then 15th term is

If the 9^(th) terms of an A.P is zero , prove that 29^(th) term is double the 19^(th) term .

If 6 times the 6^(th) term of an A.P, is equal to 9 times the 9^(th) term, show that its 15^(th) term is zero.

If 6 times the 6^(th) term of an A.P, is equal to 9 times the 9^(th) term, show that its 15^(th) term is zero.

If in an A.P. 7th term is 9 and 9th term is 7, then find 16th term.

If 9^(th) term of an A.P is zero, prove that its 29^(th) term is double the 19^(th) term.

If 9^(th) term of an A.P. is zero, prove that its 29^(th) term is double the 19^(th) term.

If the p^(th) term if an A.P. is q and the q^(th) term of an A.P is p then the r^(th) term is

The 7^(th) term of an A.P. is 5 times the first term and its 9^(th) term exceeds twice the 4^(th) term by 1 . The first term of the A.P. is

The 6^(th) term of an A.P. is -10 and the 10^(th) term is -26 .Determine the 15^(th) term of the A.P.
